your mom's visa is valid for 1 year with multi entries allowed within the year.
Whether she is allowed to enter US and how long she can stay depends on the immigration officer at the port/airport. It is pure luck and unpredictable.
But certainly I would not try to fly to US one day before the visa expires.
